The Met’s catalogue: a portrait of Antoninus Pius

Date in the source: ca. 138–161 CE; API numeric search bounds 100–199

The Metropolitan Museum of Art catalogue identifies object 253386 (accession 33.11.3) as “Marble portrait of the emperor Antoninus Pius”, assigns the cultural label “Roman”, gives the material as “Marble”, and displays the date “ca. 138–161 CE”.

What this does and does not establish: A source-attributed catalogue description, not independently established material, identity, origin or exact manufacture date. No image or physical object was inspected. The API numeric bounds are 100–199, broader than its displayed approximate date ca. 138–161 CE; this discrepancy is retained, not resolved. Navigation uses the broader API bounds only as an approximate discovery interval.

The Met’s catalogue: a trumpet

Date in the source: 100–800; API numeric search bounds 100–800

The Metropolitan Museum of Art catalogue identifies object 501851 (accession 89.4.1285) as “Trumpet”, assigns the cultural label “Moche”, gives the material as “Clay”, and displays the date “100–800”.

What this does and does not establish: A source-attributed catalogue description, not independently established material, identity, origin or exact manufacture date. No image or physical object was inspected. The broad 100–800 range is not evidence for activity in every intervening year. The museum country field is a present-day geographic locator, not a claim of an ancient national border.
